    ha oh well see how it goes I guess can't really make them any smaller.

    Check your data sheet for minimum gaps Widths etc. The gap and tooth dont have to be the same. The tooth can be say 3mm wide and the gap 10mm to get the dimensions you need.

    Just make it from mild steel and paint it. You can do stainless but it needs to be a certain type And ive forgotten what grade.

    Id go 24 teeth for better resolution. Remember thats at cam speed so its really only 6 teeth. we make them 24 tooth and have 2 missing teeth 180deg apart when I do an rb and replace the factory trigger wheel. set it up as crank speed 12-1

    both will work fine. Yeah people say that but there's factory ecu's mainly euros bmw etc that have the igniters built into the ecu's no problems as long as there's good grounding. best thing about the bip373 is over current protection is built into them so if you over dwell your coils they'll shut down untill the cool down first.

    Ditch that ignitor and just add another bip373 to spark b. Or you can use it and ditch the bip373 you already have and use that ignitor bear in mind its probably 20 years old.

    You'll need 2 bip373's one to drive each set of coils. spark a and spark b Not sure if you have room but i recently did this for an evo motor that had been rwd'd and couldn't use the dizzy trigger any more. Basically machined the rear of the bottom pulley into 24 teeth and mounted the hall effect sensor in behind it. There is also another hall effect sensor on the cam looking at a single cap screw for the sync pulse as its sequential.
